T 0 all whom it nuty concern:

Be it known that I, J ULES FLORIN, a citizen of the French Republic,residing at Roubaix, France, have invented a certain new and usefulImproved Method for the Manufacture of Woven Fabrics Adapted for Usewith Machinery, of which the following is a specification.

This invention relates to the manufacture of woven fabrics for use withmachinery said fabrics being made from woolen yarns or other animalfibers, (mixed with vegetable fibers or not,) and the essential featuresof said fabrics are that they are unshrinkable and of a maximum andnormal resistance in the direction of revolution of the machine parts towhich they are applied, being unstretchable and of great tensilestrength.

Fulled woolen fabrics used for the purposes stated have the followingdisadvantages when subjected to pressure-tension or moisture: Forinstance, when used as a sleeve or covering for a roller or othermachine part they become thick or felted and hard, and then adhesion tosaid roller or part is unsatisfactory. Hitherto for the purpose ofobtaining proper adhesion the sleeve or covering is made of a smallerdiameter than that of the roller, and by expanding it by hand and takingadvantage of the elasticity of the fabric the said covering may beapplied to a roller of considerablylarger diameter. It will therefore beseen that the adhesion on the roller is stronger in the proportion asthe diameter of the covering is smaller; but the pressure exercised by afulled fabric depends on the degree of fulling and frequently permitssaid sleeve or covering to slide or revolve on the roller, so that itstexture becomes distorted.

When a fulled fabric is used as a feed-band or conveyor, which must bearcertain strains or traction, the said fabric is liable to stretch andends by breaking after having worked badly, and, again, for instance,when used as the blanket in paper-making machines it becomes increasedin length, reduced in width, and loses its filtering properties.

It is known that elements of the halogen groupviz. chlorin, bromin, andiodinrender wool unshrinkable; but it is impossible to treat the fabricswith these substances after their manufacture for the following reasons:first, because said fabrics being usually of great thickness thesubstances mentioned would not penetrate through them and would only actinefficiently on their surfaces, and,

pletely-fulled fabrics the maximum and nor mal resistance could not beobtained, Which is necessary for pressing the coverings on the rollersor giving the fabric the necessary tensile strength when used as a bandor apron.

The invention consists in producing the new fabric by renderingunshrinkable the animal yarns or fibers used, for intance, as weft-yarnsin the manufacture of such fabric by treating them with chlorin, bromin,or iodin, the warp being formed by similar but untreated yarns, or viceversa, and after weaving the fulling is carried out, as usual. By thismeans a fabric is obtained which is only fulled in one direction ,butwhich is compact, of considerable thickness and solidity, supple, andvery suitable for use in connection with machinery.

The advantages obtained by this improved method of manufacture are asfollows: The fabric has the necessary qualities for rotary work, andespecially with moist substances or in moist surroundings, since it issolid and at the same time supple, and its elasticity will remainbecause the fabric is unshrinkable and unstretchable in the direction ofits rotation. The fabric offers great resistance to tension andpressure, since the strains are taken up by the elasticity of thetreated yarns, the latter being present in an unfulled condition in thefulled fabric. When used for packing or filtering purposes, the fabricis rendered hygroscopic by the methad employed, and its dimensions canbe calculated in a mathematical manner, since the yarns do not becomethick or felted, and in copying any given piece of the fabric it issufficient to use the same number of yarns in order to exactly reproducethe original dimensions, which is a great advantage, considering thatotherwise said reproduction depends on the degree of fulling. Owing toits qualities of tension and contraction, which can be exercised in anormal and maximum manner,due to the elasticity of the yarn itselfandalso owing to its mathematical reproduction, this non-stretchable fabriccan also be employed in a dry state or in dry surroundings.

If it should be necessary in certain cases when the fabric is finishedand fulled, the warp could be superficially treated with chlorin,bromin, or iodin on the surface of the fabric where the yarn is exposed.

The improved fabric may be used as a muff or sleeve covering for therollers in the dressing ICC of fabrics or sizing of paper, also in themanufacture of paper as a covering for the presthe dressing or ironingof linen as a sleeve for sure-rollers and as a conveyer or blanket,incovering the rollers of the machines therefor, in rotaryprinting-machines, especially those for printing in colors, as sleevesor cylindercovers, blankets, and the like, and generally in allindustries and every application where one or more qualities of theimproved fabric is or are necessary.

What I claim as my invention, and desire to secure by Letters Patent, is

1. Process for the manufacture of woven fabrics, consisting in treatingsome of the yarns with an element of the halogen group, weaving, andsubsequently shrinking the untreated yarns by fulling substantially asdescribed.

2. Process for the manufacture of Woven fabrics consisting in treatingone series of yarns with an element of the halogen group, weaving, andsubsequently shrinking the untreated series of yarns by fullingsubstantially as described.

3. Process for the manufacture of woven fabrics consisting in treatingcertain yarns of one series with an element of the halogen fabrics,consisting in treating some of the yarns with an element of the halogengroup, Weaving, shrinking the untreated yarns by fulling andsubsequently superficially treating said untreated yarns with theaforesaid halogen element substantially as described.

6. Process for the manufacture of woven fabrics consisting in treatingthe Weft-yarns.

with an element of the halogen grou Weaving, shrinking the warp-yarns byful ing, and subsequently treating said warp-yarns with the aforesaidhalogen element substantially as described.

In witness whereof I have signed this specification in the presence oftwo witnesses.
